SEMICONDUCTOR TECHNICAL DATA L SUFFIX CERAMIC CASE 620 The MC14532B is constructed with complementary MOS (CMOS) enhancement mode devices. The primary function of a priority encoder is to provide a binary address for the active input with the highest priority. Eight data inputs (D0 thru D7) and an enable input (Ein) are provided. Five outputs are available, three are address outputs (Q0 thru Q2), one group select (GS) and one enable output (Eout). • Diode Protection on All Inputs • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low–power TTL Loads or One Low–Power Schottky TTL Load over the Rated Temperature Range ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ P SUFFIX PLASTIC CASE 648 D SUFFIX SOIC CASE 751B MAXIMUM RATINGS* (Voltages Referenced to VSS) Parameter Symbol VDD DC Supply Voltage Value Unit – 0.5 to + 18.0 V Vin, Vout Input or Output Voltage (DC or Transient) – 0.5 to VDD + 0.5 V Iin, Iout Input or Output Current (DC or Transient), per Pin ± 10 mA PD Power Dissipation, per Package† Tstg Storage Temperature TL ORDERING INFORMATION MC14XXXBCP MC14XXXBCL MC14XXXBD Plastic Ceramic SOIC TA = – 55° to 125°C for all packages. 500 mW – 65 to + 150 _C 260 _C Lead Temperature (8–Second Soldering) PIN ASSIGNMENT * Maximum Ratings are those values beyond which damage to the device may occur. †Temperature Derating: Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C Ceramic “L” Packages: – 12 mW/_C From 100_C To 125_C D4 1 16 VDD D5 2 15 Eout D6 3 14 GS TRUTH TABLE D7 4 13 D3 Ein 5 12 D2 Input Ein D7 D6 D5 D4 Output D3 D2 D1 D0 GS Q2 Q1 Q0 Eout 0 1 X 0 X 0 X 0 X 0 X 0 X 0 X 0 X 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 0 0 0 X 1 0 0 X X 1 0 X X X 1 X X X X X X X X X X X X X X X X 1 1 1 1 1 1 1 1 1 1 0 0 1 0 1 0 0 0 0 0 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 X 1 0 0 X X 1 0 X X X 1 1 1 1 1 0 0 0 0 1 1 0 0 1 0 1 0 0 0 0 0 Q2 6 11 D1 Q1 7 10 D0 VSS 8 9 Q0 X = Don’t Care This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.

Two MC14532B’s Cascaded for 4–Bit Output VDD VSS E R CLOCK INPUT C DIGITAL TO ANALOG CONVERSION The digital eight–bit word to be converted is applied to the inputs of the MC14512 with the most significant bit at X7 and the least significant bit at X0. A clock input of up to 2.5 MHz (at VDD = 10 V) is applied to the MC14520B. A compromise between I bias for the MC1710 and ∆R between N and P–channel outputs gives a value of R of 33 k ohms. In order to filter out the switching frequencies, RC should be about 1.0 ms (if R = 33 k ohms, C 0.03 µF). The analog 3.0 dB bandwidth would then be dc to 1.0 kHz. Q1 [ ANALOG TO DIGITAL CONVERSION An analog signal is applied to the analog input of the MC1710. A digital eight–bit word known to represent a digitized level less than the analog input is applied to the MC14512 as in the D to A conversion. The word is incremented at rates sufficient to allow steady state to be reached between incrementations (i.e. 3.0 ms). The output of the MC1710 will change when the digital input represents the first digitized level above the analog input. This word is the digital representation of the analog word.
